What role does this predator-prey interaction play in the overall Antarctic ecosystem dynamics?
Answer
It acts as top-down control, regulating the seal population and potentially culling the less fit individuals.
The predation exerts constant selective pressure on the seal population, favoring the fittest, and contributes to the top-down regulatory control within the Antarctic food web.
